TVS - Varistors, MOVs (Transient Voltage Suppressors) usually refers to a kind of two-terminal passive component which is protected against sudden over-voltage transient events. It bridges the gap between two conductors to limit the transient voltage or current generated by over-voltage or electro-static discharge (ESD). The V140LC2PX2855 is a two-terminal, non-polar, bi-directional transient voltage suppressor, designed specifically to protect against fast transient over-voltage events. It exhibits an industry-standard 4500W (8/20µs, 10/1000µs) rating and is designed to provide both clamping protection and fast response time.The V140LC2PX2855 has a wide range of applications due to its high level of protection. It is typically installed in a circuit which is usually in close proximity to a circuit with high transient voltage, such as near lightning strikes, or in areas with high ESD levels. In addition, the device can be used for spark gap protection to reduce or suppress voltage overshoot of coils used in telecommunications and industrial products.In terms of working principle, the V140LC2PX2855 functions as a Zener diode. When a transient voltage spike is applied to its electrodes, the diode\'s temperature increases due to the generated Joule heat. The increase in temperature causes the diode to enter its avalanche or breakdown region, thus allowing the diode to conduct current at high voltage levels. This conductive current then conditions the transient current, limiting it by offering a lower resistance path to the current. The diode then dissipates the energy as heat, providing the primary protection from the transient voltage event.The V140LC2PX2855 is also designed for use in automotive applications. It is designed to absorb high voltage spikes caused by electrostatic discharges, which are an increasingly important issue in automotive electronics. It also offers excellent performance in audio systems and high-end automotive applications which demand zero in-rush and over-voltage conditions. In addition, the device is also suitable for use in direct sunlight applications, as it has excellent light and heat stability.The V140LC2PX2855 is highly reliable and offers a low on-resistance for efficient operation in all conditions. It is also RoHS compliant and designed to meet automotive safety standards. Overall, the device provides the highest level of protection, ensuring safety and reliability.
